Application filed July 3, 19!)7. Serial No. 382,056.

To all whom it may concern:

Be it known that 1, Louis OPPENHEIM, a citizen of the United States, residing at New York city, Manhattan, county and State of New York, have invented new and useful Improvements in Water Closet Seats, of which the following is aspecification.

Thisinvention relates to a Water closet seat which is so constructed that the sections of which the seat is composed are thoroughly interlocked and that the 'oints between said sections cannot open un er the influence of shrinkage, strain or moisture.

In the accompanying drawing: Figure 1 is a plan of-my improved water closet seat; Fig. 2 an end view thereof; Fig. 3 an enlarged section on line 33, Fig. 1; Fig. 4 an enlarged end view of one of the side pieces, and 5 a similar view of one of the end pieces.

he closet seat is composed of two wooden side sections 10, and two interposed wooden end sections 11 as usual. The side sections 10' are provided along each end of their inner edge with a tongue 12 which is made flaring in cross section, (Fig. 3), and Wedge-shaped in longitudinal section or face view, (Fig. 4).

The taper oi. tongues is preferably such that they gra ually widen towards the on ter edge of the end sections, where they attain their maximum cross section. Each tongue 12 is rovided with a socket for the'reception of a ocking pin 13, pressedoutward by a spring 14.

The end sections 11 have at each edge a groove 15 which is so shaped that it will accommodate tongue 12. That is to say, each groove is undercut in transverse section, (Fig. 3), and tapers in longitudinal section or face view, (Fig. 5). Into each groove. opens a socket 16' adapted to become alined with pin .13, so as to receive the same.

In assembling the parts, the side sections 1.0 are placed into parallelism and at a distance apart equal substantially to the length of the end sections. The latter are arranged at right angles to the side sections and with the inner ends of tongues 12. 'lhe sections are now moved outward alone snch tongues, (the pins 13 heing temporarily depressed by hand), until the outer edge of the end sections is flush with the corresponding edge of the side sections, when further move: ment will be prevented by the ta ering shape of the tongues and grooves. W ion the end sections have thus arrived at their correct position, sockets 16 will become alined with the pins 13, (which have meanwhile been re leased), so that the pins will be projected by their springs 14., into' the sockets. In this way all the parts of the seat will become permanently interlocked and any spreading of scams under the influence of heat 01' mi ture is prevented.

I claim:

1. In a closet seat,side sections each having sockets, end sections between the side grooves 15 are brought into engagement sections, each end section having a socket upon each side for alinement with the corre v 7 0 sponding sockets of the side sections, and locking devices carried by one set or sockets for automatic proljection into the other set] of'sockets when tie sections are assembled to lock the sections together ermanently, said locking devices being wholly confined. within the assembled sections against n2ai1ipulation. i

2. In a closet seat, side sections having Wedge-shaped tongues provided with sockets, end sections havin wedge-shaped grooves upon each side and each provided with a socket, and spring pressed locking ins seated in the sockets of the side sections or projec tion into the sockets of the end pieces when the sections are assembled to lock the sections together permanently.

Signed by me at New York city, (Manhattan), N. Y., this 1st day of July, 1907.
